Abstract

The invention relates to an apparatus (100) for sifting feedstock (1), comprising: a. a static sifter (2) that has a ventilated bottom (4) which is oriented at an angle to the vertical and is penetrated by sifting gas (3); b. an inlet (9) for feeding the feedstock (1) to the ventilated bottom; c. (4) an outlet (10) for the coarse material; d. a dynamic sifter (5) that is mounted downstream and encompasses at least one rotor (6) with rotor blades (15) and a horizontal rotor axis; e. at least one outlet (19) for the sifting gas loaded with fine material; and f. a housing (8) inside which the static and the dynamic sifter (5) are arranged. The housing area surrounding the dynamic sifter is designed as a housing spiral such that the sifting gas (3) flows against the rotor (6) in a substantially tangential direction. The rotor (6) rotates (14) counter to the direction of flow of the sifting gas (3) in the housing spiral.
